A multi-proxy study of changing environmental conditions in a Younger Dryas sequence in southwestern Manitoba, Canada — Comment on the paper by Teller et al., Quaternary Research Volume 93, 60–87

A multi-proxy study of changing environmental conditions in a Younger Dryas sequence in southwestern Manitoba, Canada: Response to comments by Breslawski et al., Quaternary Research Volume 94, 210–211

“…Breslawski et al (2020) are correct. Although UCIAMS-88701 is correctly reported in Table 1 of Teller et al (2019), the lab number for the same radiocarbon date is incorrectly listed on p. 68 as PSUAMS-8870.…”

“…Breslawski et al (2020) claim to have found inconsistencies in Teller et al (2019) in the reporting of radiocarbon dates associated with the Younger Dryas Boundary (YDB) layer. We address those points one by one below.…”

“…We address those points one by one below. Bolded sentences are directly quoted from Breslawski et al (2019).…”

“…Teller et al (2019) and others discuss this problem. Breslawski et al (2020) identified 15 dates (58% of the 25 dates we used) that sit outside the 95% envelope, and conclude that they indicate “severe age reversal issues.” There is simply far too much uncertainty in radiocarbon dating and age–depth modeling for Breslawski et al to claim that a precision of ± 20 years is required in order for our model to be correct.…”
